CHICAGO — Could red light cameras be used to give out parking tickets, too?

The City of Chicago, while searching for a new vendor to operate its controversial Red Light Camera program, is asking bidders for ideas on how else to use the cameras, including spotting parking violators.

The city insists it's just asking at this point and has no plans to use the red light cameras to ticket drivers for anything other than running red lights.

But one critic said the aggressiveness of the city's camera enforcement "makes my hair stand on end."

“I would think they’re looking at it to see if it is possible — they’d like to know from camera companies if you can do it. What makes my hair stand on end is the sheer aggressiveness of their camera enforcement,” Walker said.

The city recently released a request for proposal for a new red light camera vendor. Amid the program overview, bidding guidelines, legal requirements and exhibits, the request for proposal asks potential vendors to include ideas on how their camera technology could be adapted to do double duty for spotting parking and other traffic violations.

"The Respondent should indicate if and how the proposed automated Red-Light enforcement system could also provide other automated enforcement of other traffic or parking violations such as rush hour restrictions, maximum parking time, exclusive lane violations," according to the request for proposal.

The document does note: "The City does not currently intend to implement automated enforcement of these services."

Bill McCaffrey, spokesman for the city's Department of Procurement Services, brushed off the idea that the red light cameras will be asked to do more.

"As stated in section 2-11, we do not intend to use the red light cameras to enforce any other violations," McCaffrey said. "The RFP process is a great opportunity to gain a wider understanding of available technology in a rapidly advancing field."

But it was traffic data gained from using the city's own red light cameras to document speeding incidents that helped persuade city officials that speed camera enforcement could have a place on Chicago streets. That speed camera enforcement program is coming soon.

New technology in red light and speed cameras has the ability to see hundreds of feet down streets and sometimes in all directions.

Experts have said if cameras can catch the license plate of a vehicle speeding or running a red light, it can certainly identify a car parked illegally in a tow zone, at a bus stop or in violation of Chicago's winter parking ban.

Walker, whose nonprofit group is opposed to the use of automated enforcement camera technology on motorists, said adding this type of enhanced enforcement ability to red light cameras is feasible.

“That would be a system functionality that would not be that hard to make work,” said Walker. “You could use it for searching for vehicles with three or more parking tickets to boot it.”

Chicago's red light camera program has generated $375 million for the city since its start 10 years ago. Walker said preserving the tens of millions of dollars the city receives from Red Light Camera fines every year is the driving force behind the city’s interest.

“I believe they are absolutely addicted to the level of revenue they generate and are afraid to lose any significant portion of it,” Walker said. “They’re going to try to keep the revenue flow going and possibly extend it. It’s a scary proposal.”

Walker said he believes Chicago is just hedging its bets by having another possible revenue stream in case traditional red light camera revenue takes a hit, pointing to a freshly introduced bill in Springfield.

The “One Second For Safety” bill sponsored by state Sen. Dan Duffy (R-Lake Barrington), would force municipalities to add one second to the yellow light intervals at traffic intersections equipped with red light cameras.

Studies seem to show adding more time to the yellow light allows more drivers to legally and safely make it through an intersection.

In other states and cities where the practice has been used, red light running fell significantly, and safety improved. As a result, red light camera revenue declined. When Duffy proposed the bill last year, lobbyists for the City of Chicago actively opposed the bill.

University of Illinois Chicago professor Rajiv Shah, who studies the role of cameras and surveillance in society, finds this potential expanded use of camera enforcement part of the natural progression of the technology.

“I’m not at all surprised by it,” Shah said, explaining camera technology has advanced significantly in the 10 years since Chicago first adopted red light cameras.“I think they would have done it 20 years ago if they could. To me it’s the natural extension of the technology as the cameras become more sophisticated. I think that would be a natural entré into other things.”

Shah also foresees Chicago integrating its red light cameras into the city’s already robust network of surveillance cameras administered by the Office of Emergency Management and Communication and allowing the city's 384 cameras to serve as a means to track vehicles in real time.

“If you could tie them into a real-time system, you could track cars through the entire city,” Shah said. “OEMC would see it as another tool. You could use the license plate-recognition technology to track stolen cars, locate vehicles with over three parking tickets and identify uninsured motorists. Think about it: You almost have a Big Brother system following cars around.”

Identifying uninsured vehicles and issuing fines via the city’s Red Light Camera system was an idea proposed by Ald. Ed Burke in 2009.

But the latest request for proposal seems to reveal some other potential issues or challenges for the city and a new red light camera vendor.

Due to the recent bribery scandal, current red light camera vendor Redflex Traffic Systems which has held the contract since the program’s inception in 2003, may continue to haunt the city.

That’s because, unlike most city Red Light Camera programs where the vendor provides the cameras for free or leases the cameras monthly, Chicago purchased their cameras from Redflex outright.

This was considered forward thinking on the part of the city, as typically when the camera companies provide the hardware to a municipality for free, they take an often significant cut of the ticket revenue. Chicago does not currently share revenue generated by fines with Redflex, but pays on a fee-based schedule.

Chicago spent tens of millions of dollars to buy its 384 red light cameras and associated hardware. While the city licenses software from Redflex to operate the cameras, there are propriety restrictions that may make it difficult at best, and impossible at worst, for a new vendor to utilize the current camera infrastructure long-term. Some camera companies do not use the same in-ground sensors which trigger Redflex's cameras. Several companies utilize laser technology or video to sense when a vehicle has run a red light.

The city all but admits it may have to replace its current cameras as it asks vendors to submit two proposals — one where the city owns the cameras and another where the vendor retains ownership of the hardware.

"As is best practice, we are exploring all options before deciding on a new vendor to ensure we obtain the best deal for taxpayers and residents," said McCaffrey.
